a cum, (oi. ass-55y My present invention relates to slip covers the provision of a slip closure for the end, or no ends,,of a tubularpaper container body, and which closure includes two depending flanges. so spaced apart as to frictionally engage.- and 1 bind against the'outer and'inner walls of the 8 container body so 'as to securely hold the closure in position andagainst accidental displacement on the end of the body. a

A further object of the invention resides in the provision of a slip closure embodying two so cover portions having spaced depending flanges adapted to frictionally engage the outerand in- .nerwalls eta-tubular paper containerbodyapplied to the end the two cover portions .together by means of a zdsifternozzle. IA still further object of'th invention is-the provision of a slip cover for paper bodied containers, which possesses advantages in points of simplicity and eiliciency, and, at the same time proves itself comparatively inexpensive in cost of manufacture.

With the above-and other objects in view, the invention consists in the novel. features of construction, arrangement and combination of parts hereinafter more fully described and'flnally pointed out in the claims hereto appended.

In the drawings, the reference character I designates a tubular any suitable shape such, for instance, as cylindrical, oval, oblong, square, and the like, and which is normally open at both ends thereof. Thus, the body is in the nature or form of a bottom closure 2 of the usual tightly within one end of the it is provided with a peper tube. A suitable metal container body, and,

:ripheral flange 3 which is crimped over the end of the container and into engagement with the 15 outer face thereof. b

The closure for the opposite, or upper end of the container body and embodying features of my invention, is designed as a slip type of 010- sure'so that it can be easily and readily applied, without the aid of a crimping device, to the top of the container thebody has been filled with powder, or the like.

The top closure, in one embodiment thereof, cas one within the other. The outer of the two caps includes a cover portion 4 and a peripheral flange'portion r5 dependingdownwardly therefrom. The inner of the two capsincludes a cover portion 8 and a peripheral flan portlonl projecting down- The .two cover portions 4 and other, and, in one embodiprovided with regiswardly therefromi merit of the invention are 8 and 3, respectively, and there nozzle including a body portion ll open at its lower end and crimped at its lower edge into engagementwith the lower face'ofthe inner cover portion 8. The body It is formed with an outwardly projecting bead ll engagement with'the upper face of theouter cover portion 4. The upper end of the nozzle body II is closed and-provided with suitable like opening! it. The nozzle may be detachable slip closure ,ll; "lhesifternoasle may be eliminated, if desired, and in such instance, the cover portions maybeconnected by means of a suitable fastening-.device such, for instance, as by arivet ll.

'ihe-flanges respectively, a e concentrically spacedapartsoastowceive the end portion of the of a paper con-' paper container body or 10 In applying the slip cover to the end of a paper container body, it will be apparent, that force is employed in doing so, and as the closure is forced down to home position, the cover flange i frictionally engages the outer wall of the con- 15 engages the inner wall of the container body, and, in so doing, suiflciently squeezes the paper body material to provide a tight flt between the slip closure on the end of the container body, thus assuring it against accidental displacement, or removal from the end of the can body. I

Referring to the modification, shownin Fig. 6, the can closure embodies two apertured cover portions 4 and C, respectively, having the depending flanges I and 1, respectively, and which apertured cover portions are provided with a sifter nozzle l0 and secured thereto in any suitable manner such, for instance, as shown in Fig. 1. The depending flange 1 of the cover portion 6, it will be observed, is provided with a plurality of outwardly projecting protuberanc'es I which are adapted to ofl'er additional resistance to the removal of the closure from the end of a can body, due to the protuberance flrmly gripping the inner wall of the can body I when applying the closure to the end of a paper or flbrous can body. Referring tothe modification shown in Fig. 7, the can closure embodies the apertured cover portion 4 having the depending flange 5, as shown 0 in Fig. 1, and which cover portion is provided with a sifter nozzle ll secured thereto in any suitable manner such, for instance, as shown in Fig. 1. Instead of the cover member and its flange 1 being associated therewith as shown in Fig.1,

' i I employ a ring-like inner cover portion 6', from the outer peripheral edge of which depends a flange 1' which isinclined relative to the flange I i from its junction with the cover-portion 8' so as to provide a substantially wedge-shaped recess I, I! or can body wall receiving space ll between the closure flanges I and The inner cover ring 0' and its flange 1' are secured in pomtion within the outer cover portion 4 and its flange l by pressing the metal at or adjacent the junction of the 1-" cover ring I and. the flange I outwardly into tight frictional contact with the inner wall of the cover flange I toprovide what-may be termed a press flt at this point. Inthis modification, it

is apparent that the material of the can body is compressed when forcing the closure onto the end of a paper'can body I.

, Referring to the modification shownin Fig. 8, it-willbeobmrved, that the closure embodies the outer apertured cover portion 4 and its depend- "ing flange as shown inPlg. 1. Instead of the cover portio [and itswlepending flange l, as shown in mg. 1, or the cdverring 0' and its inclined flange or funnel-aha flange I, as shown \7 in Fig.1, I employ an inner pertured cover portion, which terminata in an outwardly down-- wardly projecting body portion II, which terinmates at its lower end in anupwardly and out-.

wardlyprojecting flange ll, the upper free edge 7 ll of which is suitably spaced from-the inner wall tainer body, and, the cover flange l frictionallyof thecover flange to provide an annular space l5 between the inner walls of the flanges] and,

I8 to receive the wall of a paper can body when the closure is forced into position on the end of the can body. In this instance, it will be ob served that the upper edge ofthe flange it, which is more or less raw,-flrmly grips the inner wall of a paper can body I to assist the outer cover flange 5 in securely holding the closure in position.

. In either form of the invention, it will be observed that I provide a vertical annular space between the inner cover flange and the outer cover flange to receive the wall of a paper can body when the closure is positioned on the end of a can body. Furthe it will be apparent that in either instance, I p ovide a closure which in reality is a combined slip andfriction type of closure, as theouter cover flanges slip over and engage the outer wall of the can body as an ordinary slip cover, and the inner cover flange has a iriction'flt with the inner wall of a can body, as an ordinary friction type of closure.

Either the top, or the top and the bottom of a container body can-be provided with the double flanged slip closure, herein described. However, if both ends of the body are so equipped, the bottom. closure is not provided witha sitter nozzle. 7 The many advantages of the herein describedv invention will readily suggest themselves to,those skilled in the art to which it appertains.

From the foregoing description, it is evident that a simple device for thispurpose has been disclosed, but it is to be lmderstood that I do not'desire to're'strict, or limit myself to the very details of the'construction shown and described,

.. which is merely illustrative, it being obvious that changes, not involving the. exercise of invention,-
